- Description
-
Bitternut Hickory is a tall, slender, cylindrical deciduous tree with a broad pyramid-shaped crown. It is native to North Carolina and usually found on moist, rich soils in relatively open areas where the tree can find sun. The Bitternut Hickory does not tolerate shade but will tolerate a variety of soil types. The tree has a strong tap-root, making it difficult to move, and needs a lot of space as it matures; all considerations for planting in a permanent position. When surrounded by other trees, the trunk is long and straight and the crown is short; in open areas, the trunk is less long and the crown larger and ovoid in shape. At all seasons, the Bitternut Hickory can be identified from all other native trees by its long, scaly, yellow buds. On bottomlands, it develops into a tree of 50 to 70 feet or more with a straight trunk, 1 to 2 1/2 feet in diameter. The wood is hard, strong and heavy, with a reddish-brown heartwood. This tree is late coming into leaf and loses its leaves early in the autumn, but while the leaves are present, it casts an open shade allowing lawn or other plants to grow beneath it. Individual trees have been known to live up to 200 years; however, they do not produce nuts until at least 30 years old.
A food source for the larvae of the Luna (Actias luna) and the Hickory Horndevil (Citheronia regalis) moths.
Insects, Diseaes, and Other Plant Problems: Bark beetle, pecan weevil, borers and twig girdler are sometimes problems. White heart rot, anthracnose, leaf blotch, powdery mildew, leaf spot, catkin blight and crown gall are occasional diseases. This tree is shade intolerant. Hickory
